PATENT OFFICE ERNEST JOSEPH runny, OF'BIR-MINGHAM, ENGLAND LOOM FOR WEAVIITG CARPE'IS AND LI KE FABRICS Application filed. May 11, 1929, Serial No; 362,195, and in Great Britain July 18, 1928.

Thisninvention has reference to looms for weaving AXminster carpets and like tufted pilev fabrics and is an improvement in or modification of the invention setforth in the specification accompanying my prior Patent No. 1,718,486 datedJune 25,1929.

My present invention is designedto pro vide animproved method and means of locking and rigidly holding the sectional tuftyarntube and spool carrier'frames upon the foundation case or frame, with the. object mainly ofrendering the mounting of each individual sectional frame. independent of that of the adjacent sectional frame or 1 frames,

and with the further objects of reducing the cost of the sectional frames, and facilitating the necessary manipulation of the same.

According to the present invention the sectional tube and spool carrier frames'are provided with bearing plates adapted for locating engagement with the foundation case or frame and are adapted to be rigidly secured in position by locking devices provided on the foundation caseor frame. Said locking device preferably comprises a spring-pressed tooth or detent which cooperates removably with a notch in the respective bearing plate so asto be adapted to press the latter into close engagement with the foundation case or 3 frame, the tooth or detent being provided integrally on a flexible spring blade secured to the'foundationcase or frame, and its look ing action being controlled by alever or the like through the medium of a slide and incline, or other intermediate mechanism, and

said lever or the like being arranged if desired for simultaneous control of locking devices operating respectively at or towards opposite ends of the sectional frame.

In order that the invention may be clearly understood and readily carried into practice, reference may be had to the appended explanatory sheet of drawings, upon which Fi ure 1 is a rear elevation (partly broken away of a tube and spool carrier frame having the present improvements'applie'ol.

Figure 2 is a plan of Figure 1. s

Figure 3 is an end elevation showing the foundation case or frame and one ofthe sectional tube and spool carrier frames in disassemble'drelation, the view being partly in section taken onthe line of Figure 2. Figure t'is a perspective view of a part of the foundation case or frame, showingdetails of the locking devicesthereon.

Figure'5 is' a plan view taken in section on the line '55 of Figure 1,'and also showing detailsof the locking mechanism. T

Figure 6 is a view corresponding to Fi ure 5 but showing one of the locking teet or detents withdrawn for release of its'f'respective sectional tube, and spool carrier frame. I .i In a convenient embodiment of theinvention, the foundation case or frame a i'spre'ferably of plain angular cross-section, as" de-' scribed in my above mentioned patent'provided with brackets Z) at opposite ends having springs c or other means for detachably holding the frame in the endless carrier chains. Openings or slots d are provided at longitudinally spaced intervals in one web of j the foundation frame a to permit of sectional tube and spool carrier frames 0 being hung or attached in sufiicient number to make the full 7 width required, two such sectional frames 6 being illustrated. Each sectionaltube and spool carrier frame e isprovided with sub: stantially flat endplates f having terminal proj'ectionsg with wedge-shaped extremities and having hook projectionsh at one edge, the terminal projections g being adapted to pass through the aforesaid openings (1 in the one web of the angular foundation framed, and the hook projections h being engageable $5 slidably over the edge of the other web of the angular foundation frame a, correct location of the sectional frames 6 being ensured by means of small fixed spacing plates 2' upstanding inwardly from the foundation frame, in conjunction with coengaging pairs of spacing studs j projecting slightly from the outer faces of the end plates f. Each end plate 7 is also fitted on its inner face with an apertured spring blade 70, the spoolsl being removably mounted between opposite pairs ofthese spring blades. The multiplicity of tubes carried by the sectional frames 6 are indicated at 'm. p

The sectional tube and spool carrier frames 1 e, as thus assembled and located in relationto the angular foundation frame a, are

adapted to be independently secured in position by locking means provided on the foundation frame a. For this purpose a second series of openings n is provided in pairs in the other web .of the foundation frame a, 'at longitudinally spaced intervals corresponding to the spacing of the first-'mentioned-series of openings d and of the end plates f,.and within'each of these second s'eriesof openings 7 is located a spring-pressed sliding toothor detent 0 which is adapted to engage with a notch 12 provided-ion the edge of the endjplate I f, at a point, adjacent the hook projectionfi thereon. This sliding "tooth or detent 01s inturned integrally at right angles "from the ly,"un"der the action of its flexible mounting free outer extremity of a fiexiblespring blade Q ofsubs'tantial strength, this'spring blade q being secured longitudinally-to'the outer face of there spectiveweb of'the foundation frame abymeans of a. screw stud 77 or the like passed through V the opposite extremity of the blade, the arrangement being such that the sliding .todth or' detent 0 isnormally pressed inwardblade 'g, intotight'engagement with the end plate of the sectional frame'e, the'terminal rofd t which extends longitudinally of the foundation frame and at" its outer extremity isdouble-cranked'atright angles to provide von the spring blade 9, this incline olbeing conveniently provided'by slightly bending the outer intermediate part'of the blade '9 into,

obtuse angular formation, andthe terminal slldepart u of the connectmg rod t belng accommodatedbletwee'n this incline '0 and the s adjacent face. of the foundation frame a.

V 'lThis controlling hand lever s is preferably ofdouble-end'ed form" as illustrated, pivoted at .an intermediate point w,.with an oppositelydirected pair of the connecting rods t jointed to its opposite ends, the lever 8 being thereby adapted for simultaneous releasing control ofrapair ofllocking devices operating respectively at opposite ends of the sectional frames.

I It Willbe seen that the present invention provides a means whereby each individual sectional tuft-yarn tube and spool carrier frame 6 maybe detachably'but rigidly locked a' slide u which is engageable with an incline to the foundation'case or framea, independently of the adjacent sectional frame 'or frames, and without the necessity for. the end plates 7 of adjacent sectional frames 6 being in actual contact. It will further be appreciated that these end plates f may be replaced if desired by tbearing plates,-either tWo or more in number, located in any convenient positions longitudinally of the sectional frame 6. H V 7 What I claim as my invention and desire to secure by Letters Patent is 1; A tuft-yarn spooland tube carrier device, for llSBflIl looms for 'weaving'carpets and like tufted pile fabrics, comprisinga foundation frame of the full width required adapted to be supported .at its ends, a'plurality of sectionalframes. adapted "for attachmentto said foundation frame and placed end to end thereon so asto-extend completely across the fabric, tubes joined together sideby side upon" each sectional frame, bear ngs on each sectional frame for theremovable mounting of a separate spool, bearingvplateson each sectional frame adapted for locating engage- 7 ment with said foundation frame, and "looking devices provided on said foundation frame for rigidly securing the sectional. frames in position thereon. l l
